Ground is supplied
- to driver side power window regulator terminal 2
- through power window main switch terminal 8.
Then the motor lowers the window until the switch is released.
Passenger Side Door
POWER WINDOW SUB-SWITCH OPERATION WINDOW UP
When the power window sub-switch is pressed in the up position Power is supplied
- to passenger side power window regulator terminal 2
- through power window sub-switch terminal 8.
Ground is supplied
- to passenger side power window regulator terminal 1
- through power window sub-switch terminal 9. Then the motor raises the window until the switch is released.
WINDOW DOWN
When the power window sub-switch is pressed in the down position Power is supplied
- to passenger side power window regulator terminal 1
- through power window sub-switch terminal 9. Ground is supplied
- to passenger side power window regulator terminal 2
- through power window sub-switch terminal 8. Then the motor lowers the window until the switch is released.
POWER WINDOW MAIN SWITCH OPERATION
Signal is sent
- to power window sub-switch terminal 16
- though power window main switch terminal 12.
The operation of power window after receiving the signal is as same as for operating the power window with sub-switch.
POWER WINDOW SERIAL LINK
Power window main switch power window sub-switch and BCM transmit and receive the signal by power window serial link.
The under mentioned signal is transmiffed from BCM to power window main switch.
- Driver side door switch signal.
The under mentioned signal is transmitted from BCM to power window sub-switch.
- Passenger side door switch signal.
The under mentioned signal is transmitted from power window main switch to power window sub-switch
- Passenger side door window operation signal.
- Power window control by key cylinder switch signal.
- Power window lock signal.
AUTO OPERATION
The power window AUTO feature enables the driver to open or close the window without holding the window switch in the down or up position.
POWER WINDOW LOCK
The power window lock is designed to lock operation of passenger side door window.
When the lock position power window lock signal is sent by using power window serial link from power window main switch to power window sub-switch.
Power window sub-switch by which the signal is received prohibits the operation of passenger side power window by power window sub-switch.
RETAINED POWER OPERATION
When the ignition switch is turned to the OFF position from ON or START position.
Power is supplied for 45 seconds
- to power window main switch terminal 10.
- from BCM terminal 29.
Then the power window can be operated.
The retained power operation is canceled when the driver side door is opened.
RAP signal period can be changed by CONSULT-II. Refer to "WORK SUPPORT".
ANTI-PINCH SYSTEM
Power window main switch and power window sub-switch monitors the power window regulator motor operation and the power window position (full closed or other) for driver side and passenger side power window by the signals from encoder and limit switch in power window regulator (driver side and passenger side).
When power window main switch detects interruption during the following close operation
- automatic close operation when ignition switch is in the "ON" position
- automatic close operation during retained power operation
- manual close operation during retained power operation power window main switch or power window sub-switch controls each power window regulator motor for open and the power window will be lowered about 150 mm (5.91 in).
POWER WINDOW CONTROL BY THE KEY CYLINDER SWITCH
When ignition key switch is OFF, power window can be opened or closed by turning the door key cylinder UNLOCK / LOCK position more then 1.5 second over condition.
- Power window can be opened as the door key cylinder is kept fully turning to the UNLOCK position.
- Power window can be closed as the door key cylinder is kept fully turning to the LOCK position.
The power window control operation by the key cylinder switch stops when the following operations are carried out.
- While performing open / close the window, power window is stopped at the position as the door key cylinder is placed on NEUTRAL.
- When the ignition switch is turned ON while the power window control operation by the key cylinder switch is operated.
AUTOMATIC WINDOW ADJUSTING FUNCTION
When the drivers / passengers door(s) is opened, the window of the opened door is lowered approx. 10 mm (0.39 in).
When the door is closed, the window is raised to fully-closed positions.
Automatic window adjusting function system (opening operation) does not operate when the following.
- The window is 10 mm (0.39 in) or more open from fully-closed positions.
Automatic window adjusting function system (closing operation) does not operate when the following.
- The automatic window adjusting function system (opening operation) operation.
- The keyless power window operation.
- The power window control by the key cylinder switch operation.
CAN Communication System Description
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle multiplex communication line with high data communication speed and excellent error detection ability.
Many electronic control units are equipped onto a vehicle and each control unit shares information and links with other control units during operation (not independent).
CAN Communication Unit:
CAN Communication Unit / TYPE 1:
TYPE 1:
TYPE 1:
CAN Communication Unit / TYPE 2:
TYPE 2:
TYPE 2:
In CAN communication control units are connected with 2 communication lines (CAN H line CAN L line) allowing a high rate of information transmission with less wiring. Each control unit transmits/receives data but selectively reads required data only.
